STOPPER 0R CLOSURE FOR BOTTIjES AND TE LEE.

Specification of Letters Patent.

Patented J'une2, 1908-.

Application filed. May 23, 1907. Serial No. 875,270.

To all whom it may concern:

Be it known that I, PAUL CONRAD, a subject of the Emperor of Germany, and a resident of the city of Chicago, county of Cook,

and State of Illinois, have invented certain new and useful Im rovements in Stoppers or Closures for Bott es and the Like; and. I do hereby declare that the following is a full,

clear, and exact description of the same, ref-' erence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Heretofore the stoppers or closures for bottles containin beverages, etc., frequently consist of a meta cap piece into which is fitted a tin foil blank, then a thin cork and lastly a thin sheet of paper is secured over' quiring great care in securing the same in place owing to the fact that such caps constructed of rigid metal re uire great pressure to securely engage tiem to conform with the mouth of the bottle and afford an impervious joint for leakage deteriorates the va ue of any and with most entirely IlllIlS the contents of the bottles.

It is an, object of this invention to provide a resilient closure of the class described ada ted to be easily pressed into the mouth of the bottle and which by its resiliency is firmly engaged in place affording an impervious joint.

It is also an object of this invention to eliminate the use of certain parts heretofore used and to provide a stop er which need not be fitted with exactness ut which when engaged in place entirely closes the'mouth'of the bottle and conforms thereto and locks itself in place affordinga seal both within and outside-the bottle providin a double seal.

The invention consists in t 1e matters here-- inafter described and more fully pointed out and defined in the ap ended claims.

In the drawings: igure 1 is a vertical section of a device embodying my invention showing the same in lace in the mouth of the bottle .before sealing. Fig. 2 "is a viewsimilar to Fig. 1 showing the bottle sealed assumed before insertion into the and with the flan e crimped beneath the bead. Fig. 3 is a ottom plan view of the stopper or closure. Fig. 4 is a top plan view thereof. Fig. 5 is an enlarged vertical section of the stopper illustrating the position mouth of the bottle.

As shown in the drawings: A indicates the i stopperor closure which ma be made out of any suitable metal to provi e resiliency such as tinned sheet steel or other metal having an inner layer of thin block tin a provided.

on one side thereof either as a coating by any of the well known processes, or as a separate sheet. Said stopperis formed by means of a suitable die or otherwise to afford a peripheral downturned outer flange a of any suitable length and an inner downturned portion a equal in length to the outer flange aflord ing an annular channel therebetweendnto which fits the outer-end of the neck of the bottle to a-depth coincident to the width of the bead. A horizontal portion a integrally.

connects said flange a, and ortion a and integral with the lower edge 0 the inner por-.

tion is a resilient upwardly convex or conical head portion a, which, normally forces the portion a yieldingly toward the flange a, but which yields upwardly when pressure is a plied between said flange a and ortion I a t us permitting the rim of the bott e to fit accurately'therebetween as shown'in Fig. 1.

A thin ring of cork B is secured beneath the transverse portion (1 below which may be a layer of ure tin foil if desired.

In app ying the ca or closure, it is pressed firmly upon the neck central convex head is pressed inwardly flattening the same somewhat as the outer flange is crim ed beneath the bead c at the mouth of the ottle thus firmly engaging the bottle neck within and also beneath the bead firmly locking the closure in' place and molding the soft inner layer to the surface of the bottle to perfectly seal the same.

The operation is as follows: In manufac.

of the bottle and the I While I have shown the portions connected by means of curved lines yet obviously the stopper may be constructed with angular connection and also if preferred a sheet of tin foil may be used beneath the stopper in lieu; of the cork or in combination therewith in elther case the resilient'portion clamps the flange a and portion a? tightly against the bOtt e.

Details may be varied as for'instance the annular channel may be made sufficiently wide to receive the run at the mouth of the bottle therein and the central portion greatly convexed and when the stopper is pressed in place this central portion is forced downwardly to force the portiona outwardly and thus drawtheflange inwardly to afford a double seal and ineithercase the seal is effectively made. I therefore do not desire to limit this application as to details as many changes may be made without departing from the principles of this invention.

" 3 ing covering the entire inner face of theolo- I claim as m invention:

1. A. bottle 0 osure or stopper afiording an inner and an outer seal and having aconvex portion adapted to yield upwardly.

2. A stopper or closure havin a'portion' to seal a ainst the rim of the free of 'a-bottle both inside and outside thereof, a central conical upwardly yielding portion and a linsur'e. I i

3. A device of the class described having parallel portions affording a channel'thereetween and a resilient portion forcing the parallel portions oppositely to clamp the neck ofa bottle therebetween.

' 4.. A bottle seal or closure having a channel to receive the top. of the neck of the bottle therein and resilient means adapted to clamp the closure to conform to the neck of the bottie and afiording a double seal for said bottle.

5. A closure or stopper comprising an outer downturned flange, an inner arallel portion, a transverse portion co'nnectm the same at corres ondin edges and a reel ient portion inte ra witht sinner ortion acting to force sai flange and para el ortion to firmly seal against the outside an inside of 50 tion to fit within the neck afior .11; a channel -app ied to 't portions inte therebetween arin of suitable material secured at the base o the channel, and a conical resilient portion adapted to press the flange and first named portion toward each other.

. 8. A resilient sto per or closure havin portions affording'a ouble seal and a centra portion integral with one of the sealing portions adapted to exert a pressure at all times on the sealing portions. 9. A bottle seal embracing a closure having an outer flange, a portion parallel therewith providing a space therebetween of less width than the thickness of the neck of the bottle to which applied and a portion integral with said parallel portion ada ted to yield upwardly as the closure is a pied. v

[10. closure embracin paralle connected portions ada ted to yie d o positel and a portion integra with one of t e para el por tions adapted to yield upwardly as the parallel portions yield oppositely.

11. A closure embracing parallel connected portions ada ted to clamp within and outside the nec of the bottle, a portion ada ted to Iyield. upwardly as the. closure is exerting pressure to force the portions against the bottle and a lining -for said closure conforming to the inner surface of the closure.

12. A bottle closure embracing parallel rally connected at their corresponding en s, and affording a downwardly -opening passage therebetween, a portion me object sealed and at all times,

tegral with the inner plarallel portion adapted to yield to permit sai parallel portions to be forced apart and a separate linmg for the inner surface of the cfiosure. p

13. A bottle closure embracin portions for engaging within and without t e neck at the mouth of the bottle, a central ortion exerting pressure to resist placing 't e closure in position and for forcin the inner portion against the neck of the ottle when in osition andalining of block tinor suitab e material'fo'r'the c OSIII'G.

14. Aclosureembracingparts fittingwith- 1 v in and outside the bottle, a yielding portion integral with o'ne'of said parts adapted at all times to jam said parts firmly against the i n-' side and outside o the neck of the. bottle af fording an impervious seal and alining on the inner sidezof the closure.

In testimony whereof, I have hereunto subscribed my name in the presence of two PAUL CONR' 'l subscribing witnesses.
